  Further, as shown in FIG. 6, a coin observation hole 39 is formed on the bottom surface of the change cassette 11. The hole 39 is formed so as to coincide with the arrangement position of the optical coin sensor unit 54 described above when the change cassette 11 is loaded in the loading unit 20. When the change cassette 11 is loaded in the loading unit 20, the sensor surface of the coin sensor unit 54 faces the hole 39 of the change cassette 11.

  The coin processing (coin replenishment) function and the coin erroneous replenishment prevention function in the coin processing machine 12 of the coin processing apparatus 10 having the above configuration will be described later together with the coin type discrimination function.

  Next, the configuration and operation of the coin type discriminator incorporated in the coin processor 12 will be described with reference to FIGS. The coin type discriminating apparatus is provided in the processor support unit 12B as described above.

  In FIG. 7, reference numeral 11 denotes a change cassette described above, which is a container for storing a plurality (or a large number) of coins. A plurality of coins 112 of the same type are accommodated in the change cassette 11. The change cassette 11 has an opening 33 for coin replenishment that is opened by opening a shutter (lid) 32 that can slide in the left-right direction (D) in FIG. A plurality of coins 112 of the same type are replenished and accommodated in the change cassette 11 in a fall state from above through the coin discharge part (discharge port) 17 and the coin replenishment opening 33 of the coin processor 12. The plurality of coins 112 accommodated in the change cassette 11 are accommodated in a messy state. Here, the “messy state” means a state in which each of the plurality of coins 112 is not arranged in a properly arranged state but is naturally accommodated by a fall at the time of replenishment.

  According to the coin type discriminating device, it is discriminated whether the coin stored in the change cassette 11 is a 10-yen coin or a 100-yen coin.

  As described above, when the change cassette 11 is loaded into the loading unit 19 of the coin processing machine 12 of the coin processing apparatus 10, the coin sensor unit 54 is disposed with respect to the change cassette 11. The coin sensor unit 54 is disposed at a predetermined distance below the bottom surface 115 of the change cassette 11. The coin sensor unit 54 is arranged such that its sensor surface (light emitting / receiving surface) 122 faces the hole 39 formed in the bottom surface 115 of the change cassette 11. The coin sensor unit 54 is an optical sensor incorporating a light emitting element (light emitting LED) and a light receiving element (photodiode). The hole 39 formed in the bottom surface 115 of the change cassette 11 is the aforementioned coin observation hole. The diameter of the hole 39 is set to such a size that the coin 112 does not fall downward. In the hole 39, at least one coin 112 of various accommodation modes is normally visually recognized from the outside with respect to the coin 112 accommodated in a messy state. In this case, generally, for example, as shown in FIG. 9, it is visually recognized in a state where two coins 112 are overlapped. In FIG. 9, the lower surface of the left coin 112 located on the lower side is in a horizontal state, and the lower surface of the right coin 112 located on the upper side is in an inclined state.

  The internal structure of the coin sensor unit 54 is shown in FIGS. In the coin sensor unit 54, for example, one light receiving element 123 is disposed in a hole in the center of the sensor container 125 having a circular planar shape, and further, in a ring-shaped recess around the light receiving element 123. For example, three light emitting elements 124 are arranged at angular intervals. The three light emitting elements 124 are arranged so as to be inclined at a required angle so that the light irradiation direction faces the central axis 125A of the sensor container 125. Each of the three light emitting elements 124 includes an LED that emits red light and an LED that emits blue light. Therefore, each light emitting element 124 has a configuration capable of selectively emitting red light or blue light. In FIG. 9, the sensor surface (light emitting / receiving surface) 122 of the coin sensor unit 54 faces the hole 39 of the change cassette 11. As shown in FIG. 9, a diffusion filter member 126 is disposed on the upper surface of the sensor container 125 of the coin sensor unit 54. The diffusion filter member 126 is a film-like diffusion plate that diffuses light, and preferably a product (CLAREX (registered trademark), CR-IIIC) manufactured by Nitto Resin Industry Co., Ltd. is used. The diffusion filter member 126 is composed of a circular diffusion film 126a disposed in the center portion and a ring-shaped diffusion film 126b disposed in the peripheral portion. The circular diffusion film 126a covers the opening of the hole where the light receiving element 123 is arranged, and the ring-shaped diffusion film 126b covers the opening of the ring-shaped recess where the three light emitting elements 124 are arranged. In FIG. 8, the diffusion filter member 126 on the sensor surface of the coin sensor unit 54 is removed. By providing the diffusion filter member 126 on the light emitting / receiving surface 122 of the coin sensor unit 54, it is possible to prevent regular reflection that has caused erroneous determination.

  The light emission operation of the three light emitting elements 124 of the coin sensor unit 54 is controlled by a light emission signal output from the control unit 50. For example, the three light emitting elements 124 first emit red light, then turn off the red light emission and emit blue light. Repeat it for a set time. The red light emission and the blue light emission may be continued for a certain period of time or may be blinked.

  The control unit 50 is a control unit of the processor support unit 12B as shown in FIG. 4, and is a control unit for discriminating the types of coins stored in the change cassette 11 in particular. The control unit 50 has a function of controlling the operation of the optical coin sensor unit 54 (light emitting element driving unit) and a function of processing a detection signal output from the coin sensor unit 54 (signal processing unit 141). .

  FIG. 10 shows a configuration of an electric circuit of the coin sensor unit 54. In the coin sensor unit 54, each of the three light emitting elements 124 includes a red LED 128 and a blue LED 129, and the light receiving element 123 includes a photodiode (PD). The control unit 50 includes an output line 131 that supplies power to the red LEDs 128 of the three light emitting elements 124 in common and an output line 132 that supplies power to the blue LEDs 129 of the three light emitting elements 124 in common. ing. When the light receiving element 123 receives light and generates a current, it flows into the control unit 50 via the input line 133.

  The red light or blue light generated by the light emitting operation of the light emitting element 124 passes through the diffusion film 126 b of the diffusion filter member 126 and is irradiated to the region of the hole 39, and the red light or the like is exposed to the surface of the coin 112 exposed from the hole 39. It is reflected by. The red light or blue light reflected by the surface of the coin 112 passes through the diffusion film 126 a of the diffusion filter member 126 and is received by the light receiving element 123 of the coin sensor unit 54. In this way, the surface state of the two coins 112 facing outward from the hole 39 of the change cassette 11 can be detected optically and in a non-contact manner by the coin sensor unit 54. In the signal processing unit 141 in the control unit 50, the coin exposed from the hole 39 based on the reflectance ratio characteristic of light of two wavelengths of red and blue, which will be described later, based on the light reception signal detected by the coin sensor unit 54. It is determined whether the type of 112 is a 10 yen coin or a 100 yen coin. The signal processing unit 141 is configured by a microcomputer or the like and includes a memory 142.

  Next, on the basis of the flowchart shown in FIG. 11, the coin processing (coin replenishment) function by the control unit 23, the function of discriminating the type of the coin 112 and the function of preventing coin missupply by the signal processing unit 141 of the control unit 50. explain.

  As described above, the change cassette 11 is loaded into the loading unit 20 of the processor support unit 12B, and a large number of change coins are replenished therein by the processor main body (coin counter) 12A of the coin processor 12. The change cassette 11 is determined in advance as a change cassette for 10 yen coins or a change cassette for 100 yen coins. Therefore, the change cassette 11 must be replenished with a predetermined type of coins. The processor support part 12B having the function of the coin discriminating device is configured to be added to the coin processor 12 as a preferred form of use, and is attached to the change cassette 11 by the processor body part (coin counter) 12A. This is used to determine whether or not the type of change coins that have been replenished matches the type of coins that are predetermined in the change cassette 11. In the flowchart shown in FIG. 11, a coin type discrimination process based on a coin discriminating device is incorporated in a change coin replenishment process and a coin misfeed prevention process by the coin processor 2.

  In FIG. 11, the first step S11 is a step of loading the change cassette 11 into the loading unit 20 of the processor support unit 12B. The loading is usually performed by an attendant. In the processing support unit 12B, the control unit 50 determines whether the type of the change cassette 11 loaded by the two reflection sensors 52, 53 and the identification unit 51 is a 10-yen coin cassette or a 100-yen coin cassette. The The coin type of the change cassette 11 is determined based on the change function of the change cassette type, and the determination result (change cassette type) is stored in the memory 142 of the control unit 50 (step S12). Thereafter, the coin 112 is replenished into the cassette from the opened coin replenishment opening 33 on the upper surface of the change cassette 11 based on the coin replenishment function by the processor main body 12A (step S13).

  Next, the inspection based on the coin discrimination function in the processor supporter 12B of the coin processor 12 is started. This inspection is a process of inspecting what kind of coins are replenished in the change cassette 11 in step S13. In step S14, the inspection start button provided in the operation unit 21 of the coin processor 12 is turned on. By turning on the inspection start button, the coin discriminating function of the coin discriminating apparatus of the processor support unit 12B operates.

  When the inspection start button is depressed and turned on, a drive signal is output from the output line 31 of the control unit 50. First, the three light emitting elements 124 of the coin sensor unit 54 are operated simultaneously, and the red LED 128 is first lit (step). S15). Red light emitted from the lit red LED 128 is applied to the hole 39 formed in the bottom surface 115 of the change cassette 11, reflected by the coin 112 exposed from the hole 39, and received by the light receiving element 123. As a result, a light reception signal is output from the light receiving element 123. The light reception signal of the light receiving element 123 is supplied to the signal processing unit 141 of the control unit 50 via the input line 133. In the signal processing unit 141 of the control unit 50, the reflectance related to red light is measured, for example, three times, and an average value (R) thereof is calculated and obtained (step S16). The obtained average value (R) is held in the memory 142.

  In the next step S17, the red LED 128 of the three light emitting elements 124 of the coin sensor unit 54 is turned off and the blue LED 129 is turned on based on on / off of the drive signal from the control unit 50 via the output lines 131 and 132. Let

  Thereafter, the blue light emitted from the lit blue LED 129 is irradiated to the hole 39 formed in the bottom surface 115 of the change cassette 11, reflected by the coin 112 exposed from the hole 39, and received by the light receiving element 123. The light reception signal output from the light receiving element 123 is supplied to the signal processing unit 141 of the control unit 50 via the input line 133. The signal processing unit 141 of the control unit 50 measures the reflectance for blue light, for example, three times, and calculates and obtains an average value (B) (step S18). The obtained average value (B) is held in the memory 142.

  Thereafter, the blue LEDs 129 of the three light emitting elements 124 of the coin sensor unit 54 are turned off (step S19).

  Next, a reflectance ratio (H) is calculated based on the reflectance (R) for red light and the reflectance (B) for blue light (step S20). The formula for calculating the reflectance ratio (H) is H = (RC) / (BC). Here, “C” is a measured value of each color at the darkest time. Then, it is determined whether or not the calculated reflectance ratio (H) is greater than or equal to a preset threshold value (L) (step S21). When the determination in step S21 is YES, a 10-yen coin is assumed. Judgment is made (step S22), and if it is NO, it is judged that it is a 100 yen coin (step S23).

  In the above, the threshold value (L) is determined as follows. According to this coin type discriminating function, discrimination is performed based on the hue of the coin (the wavelength of spectral monochromatic light). The basis for this is as follows. When the relationship between the specific wavelength light and the reflectance thereof is expressed for each of the 10-yen coin and the 100-yen coin, the graphs shown in FIGS. 12A and 12B are obtained. When the numerical value obtained by normalizing the reflectance (R) of the red band (long wavelength) based on the reflectance (B) of the blue band (short wavelength light) is assumed to be the above “reflectance (H)”, As shown in Table 1, it can be confirmed that the 10-yen coin and the 100-yen coin are significantly different.

  The threshold value (L) that can appropriately discriminate between the reflectance value “4.0” of the 10 yen coin and the reflectance value “1.8” of the 100 yen coin shown in Table 1 above. Is determined as appropriate.

  As described above, in steps S21, S22, and S23, when the reflectance (H) is equal to or greater than the threshold value (L), it is determined as a 10-yen coin, and when the reflectance (H) is smaller than the threshold value (L), it is a 100-yen coin. Is determined. Thus, the coin type discrimination function based on the coin discrimination device is completed.

After the above steps S22 and S23, it is determined whether the coin type discriminating result based on the coin discriminating device matches the coin cassette type storage result obtained in the previous step S12 (steps S24 and S25). ). If YES in determination step S24 following step S22, it is determined that the supply is normal (step S26), and if NO, it is determined that the supply is incorrect (step S27). If YES in determination step S25 following step S23, it is determined that normal replenishment is performed (step S26), and if NO, it is determined that replenishment is incorrect (step S27).
If it is determined that the replenishment is normal (if it matches), the replenishment process is finally permitted (step S28). If it is determined that the replenishment is incorrect (if it does not match), the replenishment process is prohibited and the process is repeated ( Step S29).

  According to the coin discriminating apparatus, blue light (short wavelength light) and red light (long wavelength light) are used as the coin sensor unit 54, and the type of coin is discriminated by hue based on the reflected light. did. The difference in reflectance between blue light and red light is clear between 10-yen coins and 100-yen coins, and the difference is that even if the coins are not in a proper posture, that is, they are tilted at an arbitrary angle. Even if a large number of coins are in a messy arrangement state, it can be detected as a clear difference. For this reason, even if it is a coin accommodated in the change cassette 11 such as a change cassette in a messy state, the type can be clearly identified.

  Further, according to the coin replenishment function and the coin erroneous replenishment prevention function by the coin processing machine 12 described above, the sheet member added to the change cassette 11, the reflection sensors 52 and 53, and the identification unit 51 are used to designate the coin cassette. The coin type is identified, and the coin sensor unit 54 and the signal processing unit 141 optically discriminate the types of coins replenished and accommodated in the change cassette 11, so that the operation of the coin counter and electrical It is possible to determine whether or not there is an erroneous supply without being linked to the.

  The configurations, shapes, sizes, and arrangement relationships described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented, and the numerical values and the compositions (materials) of the respective components Is just an example. Therefore, the present invention is not limited to the described embodiments, and can be modified in various forms without departing from the scope of the technical idea shown in the claims.

  The apparatus for preventing erroneous coin replenishment of the coin processing apparatus according to the present invention is used as an apparatus for preventing erroneous replenishment when coins designated in advance are supplied to a change cassette loaded in a ticket vending machine installed at a station.
